STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 547,256, dated October1, 1895. Application filed November 10, 1894. Serial No. 528,360. (Nomodel.) 7

To (LZZ whom it may concern.-

Be it known that I, WALTER W. HASTINGS, a citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in Winding andSetting Mechanism for Stem-l/Vinding WVatches, of which the following isa specification.

My invention relates to improvements in winding and setting mechanismsfor stemwinding watches; and the objects of my improvements aresimplicity of construction and general efficiency and convenience inuse.

In the accompanying drawings, Figure 1 is a frontelevation of the frontmovement-plate. Fig. 2 is a rear elevation of said plate with thereversible bridge removed. Fig. 3 is an enlarged sectional view on theline or o: of Fig. 1. Fig. 4 is a like View on the line y y of Fig. 1.Fig. 5 is alike view on the line 2 z of Fig. 1; and Fig. 6 is a detachedfront elevation of the reversible bridge, the same being on the scalecorresponding to that of Figs. 1 and 2.

My invention is in the nature of an improvement upon the plates forstem-winding watches, patented to me May 29, 1894, and numbered 520,483,although some parts of my improvement may be applied to other plates forstem-winding watches.

A designates the front movement-plate of a watch, which in its mainfeatures may be of any ordinary construction.

B is the reversible bridge, which is fully shown and described in myaforesaid patent. This front movement-plate is provided with partialbearings 7 on its rear side, which extend radially inward from the edgeat points designed to be immediately back of the figures 12 and 8 on thedial, and in one of these bearings the hub 8 of the beveled wheel 9 isplaced, as shown in Figs. 4 and 6. This hub is provided with an axialhole which is squared to fit the stem 10 of the watch, all substantiallyas in the aforesaid patent. The reversible bridge Bis secured upon therear or inner side of the plate A in the position indicated by thebroken line in Figs. 1 and 2, the bridge substantially covering thatportion of the plate which lies between said broken line and the outeredge of the plateA. This bridge is made attachable and detachable, so asto be changed end for end, and it is also provided with partial hub 8 ofthe beveled Wheel 9.

bearings or recesses 11 for the reception of the Both the bridge and themovement-plate are recessed for the accommodation of the beveled wheel8, as shown. Withinthebridgeisthemainspringbarrel 12 and main wheel 13,the edge of the barrel 12 being provided with notches or ratchet-teethfor being engaged withthe gear or pawl 14, and the other side ofthespring-barrel 12 is provided with a series of teeth 14:, Fig. 6, forbeing engaged with the confronting teeth on the flat side of theratchet-disk 15, which is mounted upon a square portion 16 of the shaft17 of the spring-barrel and main Wheel. This ratchet-disk is grooved onits periphery, which groove is engaged by the inner ends of thespring-fork 18, Figs. 2 and 3, and as more fully illustratedin myaforesaid patent. This spring-fork 18 is secured to the rear side of themovement-plate by means of the screw 19, and it is connected by means ofthe screw 20 with the spring-plate 21. Underneath this plate 21 is alever 22, which is fulcrumed on a pin 23, said pin being rigidly securedto the plate 21 by one end, while its other end rests loosely within theslot 24 of the lever 22, (see Fig. 4,) the position of said slot beingindicated by broken lines in Fig. 1. One end of this lever is providedwith a cam 25, Figs. 1 and 4, and the opposite end of the lever isconnected by means of a pin 26 to a curved lever or slide 27'. Thisslide works in a groove in front of the movement-plate A, and by pullingit endwise, so as to swing the lever slightly, one end will project morethan the other, and within its projecting end a screw 28 may be insertedfor an operating-handle. For convenience of illustration this curvedlever or slide is shown in Fig. 1 with both ends projecting equally. Bypulling upon the handle-screw 28 of this curved lever or slide to carrysaid slide endwise the cam on the lever 22 (see Fig. 1) will at first beswung on the arc of a circle of which the pivot 23 is the axis, therebyforcing said cam against the edge of the spring-plate 21, and by acontinued movement said cam will be forced under said spring-plate so asto raise it, thereby raising the springfork 18 and the ratchetdisk outof engagement with the spring-barrel; but when the spring-plate 21 isnot lifted by the cam 25 the ratchet-disk is in active engagement withthe spring-barrel, so that turning the stem will drive the beveled gear9 and the engaging beveled gear 29 and attached gear-wheel 30, whichengages another gear 31 on the main shaft 17, so as to drive theratchet-disk and spring-barrel in the direction to wind up themainspring.

Upon the rounded end of the shaft 17, adjacent to the ratchet-disk, isthe setting-wheel 32, the same being provided with a slightlyprojectingsquared hub 33 of a size that will readily enter the square axial holeof the ratchet-disk 15. This setting-wheel 32 enga ges the gear-wheel34, with which the ordinary dial-wheels may be connected. By operatingthe curved lever or slide 27 to disengage the ratchet-wheel from themain barrel said disk will be forced toward the squared hub of thesetting-wheel, which will enter into the square of the ratchet-disk, sothat upon turning the stem 10 of the watch to revolve the shaft 1'7 thesetting-wheel 32 will be driven with the ratchet-disk 15 at a time whensaid disk is disengaged from the spring-barrel, and is, therefore, freeto be moved in either direction for setting the hands. I mount the clickor pawl 14 upon the shaft 35, one end of which is mounted in the plate Aand the other end within the bridge B. I provide the projecting end ofthis shaft with a crank-pin 36, which crank-pin is engaged by the spring37, that is attached to the movement-plate, as shown in Fig. 1. In theposition there shown the click is engaged with the teeth of thespring-barrel 12. A part'of the movement-plate A is broken away in Fig.1 in order to show the engagement of the pawl. When it is desired to letthe spring down, this pawl may be swung outwardly to carry the crank-pinpast the center of the shaft 35, when the pressure of the spring 37 willhold the pawl out of engagement with the teeth of the spring-barrel.When the bridge is changed end for end, the click or pawl let may remainin the movement-plate and its opposite end be received within a secondorifice or bearing 38 in the bridge, which is shown in Fig. 6.

I claim as my invention 1. The combination of the spring barrel andshaft with the ratchet disk, mechanism for turning said shaft and disk,the spring plate 21 and connected mechanism for moving said ratchet diskto and from said spring barrel, the lever 22 having the cam 25, and thecurved lever or slide 27 for moving said lever 22, substantially asdescribed and for the purpose specified.

2. The combination of the spring barrel having side teeth, the shaft 21squared for a portion of its length and rounded toward its end, theratchet disk mounted on said squared portion and having side teeth forengaging the side teeth of the spring barrel, mechanism for turning saidshaft 21 and for moving said ratchet disk to and from said springbarrel, and the setting wheel 32 mounted on the rounded portion of saidshaft 21 and having a squared hub adapted to engage and disengage thesquare axial hole of said ratchet disk, substantially as described andfor the purpose specified.

3. The combination of the spring barrel and main shaft of a watchmovement with the pawl 14 mounted on the shaft 35, the crank pin 36 onthe end of said.shaft, and the spring 37 pressing upon said crank pin,substantially as described and for the purpose specified.
